Single Selection field

Single Selection fields can be used to ask from users to select one out of two or more options as an answer. This can be a "Yes" or "No" question for example or any other type of question that can be answered with one option.

Single Selection fields can be used in Prefix Formulas to customize Serial Numbers too.

The options will appear as radio buttons  when:

  • the field is Required and 
  • has up to 10 options as possible answers

The options will appear as a drop-down menu when:

  •  the field is not Required 

or 

  • when the field is Required and 
  • has more than 10 options.

Reference fields vs selection fields

Both Reference and Selection fields allow you to create lists of options. However, as these fields serve different purposes, it is important to choose the appropriate type when designing a Form.

A Selection field allows you to create a list of options inside the Form whereas a Reference field references another Form (a 'Reference Form') where each option is another Record. In the second case, as the option is an actual Record, it is possible to include more information about that option (i.e. meta-data or other kind of information) in the referenced Form. You can use as many fields as needed to capture that information and by making them Key fields you can also bring that information into the initial Form (creating the 'cascading effect').

We strongly suggest the following best practices: 

  • Use a Single Selection field to capture a basic list of options that don't require further meta-data or additional information. Examples: age categories, list of options for biological sex, etc.
  • Use a Reference field to link to a Reference Form where you will collect additional information for each option (Record). You expect changes to occur on that data (data is described as dynamic rather than static) and you need to link to these options in many Forms in your Database in a consistent way. Examples: partner organizations, list of institutions/entities, etc.
